INVALID-BED.

Specification of Letters Patent.

Pat'ented June 8, 1909.

Application filed August 24, 1908. serial No. 449,981.

To all whom 'it may ccmcem:

Be it known that I, JOHN MACKEY, a citizen of the United States, residing at Cape Horn, in the county of Skamania and State of Washington, have invented certain new and useful Improvements in Invalid-Beds, of which the following is a specification.

This invention relates to beds and has special reference' to a device of this character which is peculiarly adapted for the comfort of invalids.

An object of this invention is to provide a bed of this character with a swinging head section by means of which the patient may be raised conveniently to a sitting posture at various angles.

The invention has for a further object the provision of a table attached to the bed which may be adjusted to different angles and positions according to the requirements.

The. invention has for astill further object a pivoted head section of peculiar construction which renders it strong and durable and more adaptable to practical use than constructions heretofore employed.

Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of the complete bed, Fig. 2 is a top plan view of the same, Fig. 3 is a detailed and enlarged view of the table and its supporting means, Fig. 4 is a longitudinal Vertical section of the bed with the head section slightly raised.

Referrino' to the drawings, 10 and 11 designate the foot-board and head-board of the bed respectively which support the sides 12 and 13 between their opposite intermediate edges. The sides 12 and 13 are each recessed transversely at their inner edges as at 14 and are provided with undercut recesses 15 formed adjacent and connected to the recesses 14 at the lower edges of the sides 12 and 13. The sides 12 and 13 carry the opposite' extremities of a transverse shaft 16 which is engaged in apertures formed at the lower edges of the sides 12 and 13 and is further secured inlposition by plates 17 disposed across the under sides of the shaft 16 upon the lower' edges of the sides 12 and 13. The shaft 16 is provided with pinions 18 which are rigidly mounted upon the shaft and which extend partially into the recesses 15 formed in the inner faces of the sides 12 and 13. The shaft 16 extends beyond the side 13 Vand rigidly carries a ratchet 19 which meshes with a pawl 20 pivotally disi posed upon the outer face of the side 13 for the purpose of preventing the opposite or back'ward rotation of the shaft 16. The outer extremity of the shaft 16 is rectangularly formed for the reception of a crank arm 21 which is used for the purpose of rotating the shaft 16. Upon the inner faces of the sides 12 and 13 centrally of the shaft 16 are pivotally mounted two beams 22 and 23 which extend to the head 11 when` dropped in parallel with the sides and. which are provided withV extensions 24 to engage upon a cross brace 25 positioned transversely of the head 11. The beams 22 and 23 are strengthened by a cross beam 26 which is secured between the free extremities of the beams 22 and 23. The beams 22 and 23 are raised into various angles by means of the segmental racks 27 and 28 which are secured upon the outer faces of the beams 22 and 23 and extend downwardly into the recesses 14 formed in the inner faces of the sides 12 and 13. When the segmental racks 27 and 28 are in this position the teeth, which are formed upon the inner edge of the racks engage against the pinions 18 and are actuated thereby. The segmental racks 27 and 28 are held in position in the recesses 14 by the plates 28' which are Secured upon the inner faces of the sides 12 and 13 and extend over the slots 14 to engage the inner faces of the racks 27 and 28.

The table which is employed in connection with this bed is constructed as follows. A U shaped clamp 30 is secured to the outer face of the side 13 which is provided with a Vertical aperture extending through the same into which is positioned a rod 31 and held in such position by a pin 32 of wedge shape which is adapted to extend laterally into the clamp 30 and impinge the rod 31 against the clamp 30. At the upper extremity of the rod 31 there is positioned a horizontally disposed table 33 which is provided upon its under face with a sleeve 34 into which the upper curved extremity of the rod 31 is inserted and adjustably secured in such sleeve by a set screw 35. Vhen it is desired to raise the rod 31 to obtain a greater height of the table the pin 32 is reinoyed and the rod 31 is raised through the U shaped clainp 80 When the pin 82 i's reset and drix'en into the clanip 30 to secure a wedging of .the rod 31 Within the clainp. Then it is desired to position the table at the extreinity of the ari'n 31 the set serew 33 is lolosened and the sleeve together with the table allowed free inovenient over the upper extreniity of the same. It is thns seen that the table 53 may be readily adj usted as yto its height and horizontal position. When it is desired to raise the head section the crank arin 21 is positioned upon the shaft 16 and rotated. This rotation canses the upwardly feeding of the seginent'al racks 27 and 28 to raise the beains 22 and 23 and to thns raise the patient to a sitting` postnre at practically |the desired angle. The pawl 20 engaging the ratchet 19 holds the frame at the angle through which it is raised and prevents it froin dropping backwardly.

Vhat is cla-imed: is

s an article of niannfactnre, an invalid bed coinprising a head board, a foot board, sides disposed Vbetween said head board and said foot board, said sides having transverse arcuate recesses and nndercut recesses forined in the inner faces thereof, the reresses being` in conlnninieation With each other. a sha'l't. disposed transversely froln the nnderrnt re' eesses between said sides, pinions nionnted on the extreinities of said shaft. a ratrhet carried on one end of said shaf-t o nt\\'ardl of one o f said pinions against the onter faee of one of said sides. a pawl ('arried by said side for engageinent with said ratrhet. a Crank arin detatchably disposed on said shaft for r`tatin`' the same, beanis pirotally disposed in parallel upon the inner opposite faces of said sides` across braee carried by said head board, extensions fn'1ned on the ends of said beinns for engagelnent with `said brat-e. a cross beam carried b said beanis, seglnental raclcs depcnded front the onter ends' of said beanis and engaged in the arenate recesses in said sides and with .said pinions` and plates 1.sitioned on said sides extended over said recesses in eno'agement With said rack to hold the salne in position.
